Vigor — Petunia x hybrida

Petunia x atkinsiana D. Don

A qualitative characteristic describing the potential for vegetative mass development, shoot growth rate, and the variety's ability to fill space.

In the reference 8 varieties crop Garden petunia, where this is mentioned in the description.

The vigor of Petunia x hybrida is assessed through expert evaluation of morphometric indicators, such as plant height dynamics, bush diameter, branching intensity, and the growth rate of lateral shoots. The trait is classified by comparison with control samples into low, medium, or high vigor levels.

High vigor is characteristic of trailing series and surfinia-type petunias, which are capable of rapidly forming long shoots that require large substrate volumes and intensive mineral nutrition. Compact and bedding groups are typically characterized by medium or low vigor, focusing on bush density and uniformity.

This genetically determined trait dictates the formation management practices, including the frequency of pinching to maintain aesthetic appeal. A reduction in vigor in varieties with high potential often serves as an indicator of viral pathologies or deficiencies in growing conditions.
